Walls close in on DesJarlais

The news just keeps getting worse for embattled Tennessee GOP Rep. Scott DesJarlais, who is caught up in a messy scandal surrounding his personal life.

Opponents are already beginning to line up for 2014. The congressman was notably missing Saturday from a list of prominent state Republicans supporting Sen. Lamar Alexander’s re-election campaign – he was the only member of the Tennessee congressional delegation not asked to be a co-chair for Alexander’s bid.

Now, some of the health industry political action committees that have generously supported the former physician’s bids for Congress say they won’t contribute to his campaign anymore.

[A]t least six PACs that gave to DesJarlais’ 2012 campaign, including local insurance giants BlueCross BlueShield of Tennessee and Unum, said they won’t give again in 2014.

“Anytime you support someone, you have an association with them,” BlueCross spokesman Roy Vaughn said. “That becomes difficult if their behavior is something that doesn’t reflect well on your organization.”

Another half-dozen PACs representing health professionals, hospitals, nursing homes and health insurance companies said they haven’t decided on DesJarlais. The remaining 15 that donated to the physician-turned-congressman did not respond to a Chattanooga Times Free Press inquiry.

An abortion opponent, DesJarlais managed to win re-election in 2012 despite damaging revelations late in the campaign that he pressured a woman with whom he had an affair to get an abortion.

Not long after Election Day, the release of a transcript from his divorce proceedings compounded his problems: it was revealed that his ex-wife had two abortions and DesJarlais had sexual relationships with two patients and three co-workers while he was chief of staff at Grandview Medical Center.

The congressman, who has denied intentionally misleading voters about his past, has said he won't resign and plans to run again in two years.

But there isn’t much of a future for a member who's alienated his base, whose colleagues are keeping him at arm’s length, whose contributions are drying up and who has serious primary and general election foes waiting in the wings.
